pb with gluPartialDisk

Hi,

I’m working with an ortho2D projection and draw some primitives on the screen

I’m using glut to draw circles and arcs

For arcs I’m using gluPartialDisk but the result is not 100% what I’d like to have

This is what I do :

gluPartialDisk (qobj, 0,RADIUS_X , 180, 1,
0, 180);

I get

|/

but I don’t want to have a line connecting the ends of the arc :

``````\
|
/
``````

Is this possible to do that with glut ?
